Abstract

(57) [Summary] (Correction) [Purpose] In a thin plate press machine, blanking and drawing are performed continuously by one press machine. [Structure] This invention is a die for press thin plate processing,
In order to singularize multiple dies that require punching / drawing functions, it is necessary to configure punching and die, which are blank punching die components, with knockout, drawing punches, rings, and other drawing function components inside. It was made easy. [Effect] The die can be removed, and the number of steps in press working can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a die structure for press thin plate processing.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, when press-drawing a thin plate work material, the hoop material, which is the work material, is cut into a shape by a blank cutting die having a cutting function in FIG. The blank obtained in step 1 was shape-bent by a drawing die having a drawing function shown in FIG.

[0003]

[Problems to be solved by the device]

 However, since this structure is composed of a plurality of molds having different functions, the manufacturing cost increases when manufacturing the mold. Also, with such a structure, different machining is performed individually, so press setup is required several times, and at the same time, man-hours for molding are also required, and it is not possible to reduce the machining cost. Furthermore, it causes a problem that quality variations occur.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a punch, which is a component part of a blank punching die, having a knockout, and a die having a punching punch, a push-up ring, and the like, so that a blanking function and a drawing function are integrated into a plurality. It has a mold processing function.

[0005]

[Action]

 As a result, the number of dies required until now was reduced to a single die, and the production cost was reduced. In addition, since the number of molds is reduced to one, multiple molding processes can be performed at the same time, reducing the man-hours and the number of press setups. In addition, quality was also stabilized.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a knockout 6 part is formed inside the punch 2. The function of the spring 1 facilitates the release of this component from the material to be extruded in the downward direction of the punch 2. Further, a push-up ring 7 and a drawing punch 8 are formed inside the die 5. In this case, the ring 7 is required to be easily slidable between the inner wall surface of the die 5 and the outer wall surface of the drawing punch 8, and has a function of facilitating the release of the workpiece 3 by the function of the ring push-up pin 9. The diaphragm punch 8 is fixed to the die plate 10 and has a function of receiving the bending of the workpiece 3. That is, in the present die structure, the material 3 to be processed is shape-cut by the cutting edges of the punch 2 and the die 5, and continuously drawn on the inner wall of the punch 2 and the outer wall of the punch.

[0007]

[Effect of the device]

 As described above, the invention has made it possible to retain the drawing function in the blank punching die, so that the number of die can be deleted and at the same time, the number of press setups and the number of working steps can be easily reduced.
